Sampling helps determine whether current management strategies, such as crop rotation and use of resistant soybean varieties, are effectively reducing nematode numbers. Without testing, populations can build silently, resulting in significant long-term yield losses.

Indigo Ag today announced the commercial launch of the company’s first bionematicide for the U.S. market. Produced as a flowable powder formulation, biotrinsic Z15 is labeled for use on both corn and soybeans, requires no special equipment or training to apply and is adaptable for commercial or on-farm application.

Growing soybean varieties with a source of soybean cyst nematode (SCN) resistance other than PI 88788 can increase yields as a result of better nematode control, says Iowa State University. For improved resistance to SCN, check out this resource when selecting soybean varieties.

Now that the 2019 corn and soybean harvest is in full swing, it is not too early to start thinking about and planning for the 2020 growing season as well. For soybean farmers in Iowa, a critically important fall activity that can pay large dividends is soil sampling to determine soybean cyst nematode (SCN) population densities in fields in which soybeans will be grown in 2020.
